Abstract

A laser-operated apparatus for data and signaling recording makes use of a laser-beam source whose laser beam is directed at the Bragg angle into a tellurium dioxide monocrystal provided with an array of ultrasonic transducers, each of which is energized independently by at least one amplitude modulated very high frequency carrier. The individual transducer segments generate respective beams within the body of the crystal which, upon emerging, represent individual information channels which are separately controllable to provide the data and information recordal.

На чертеже представлена блок-схема предлагаемого устройства.The drawing shows a block diagram of the proposed device.

Устройство,дл  регистрации инфор- мадии содержит источник 1 монохроматического излучени  (лазер), первый блок 2 проецировани  светового потока , содержащий пол ризованную пластинку 3, собирающую 4 и рассеивающую 5 линзы, многоканальный модул тор 6 света, выполненный в виде монокристалла-двуокиси теллура с закрепленными на его поверхности последовательно вдоль оптической оси ультра- звуковыми преобразовател ми, входы которых  вл ютс  управл ющими входами многоканального модул тора света. Кроме того, устройство содержит второй блок 7 проецировани  светового потока, содержащий рассеиваюв1ую 8 и собирающую 9 линзы, отражательный элемент 10, например зеркало, непрозрачную оптическую заслонку 11 с закрепленным на ней фотоприемником 12, узел креплени  носител  13, выполненный в виде цилиндра с возможностью вращени  вокруг своей оси, знакогенератор 14 и блок 5 управлени , содержащий усилители 16, сумматоры 17 и формирователи 18, каждый из которых , выполнен в виде регул тора 19 уровн , ключа 20 и генератора 21 синусоидальных сигналов. Вход 22  вл етс  информационным входом устройст- ва.The device for recording information contains a monochromatic radiation source 1 (laser), the first unit 2 of the projection of the luminous flux containing a polarized plate 3, collecting 4 and scattering 5 lenses, a multichannel light modulator 6, made in the form of a single crystal-tellurium dioxide with mounted on its surface in series along the optical axis by ultrasonic transducers whose inputs are the control inputs of a multichannel light modulator. In addition, the device contains a second light projection unit 7 containing a diffusing 8 and collecting 9 lenses, a reflective element 10, for example a mirror, an opaque optical shutter 11 with a photodetector 12 attached to it, a mount unit of carrier 13 made in the form of a cylinder with the possibility of rotation around its axis, character generator 14 and control unit 5, containing amplifiers 16, adders 17 and drivers 18, each of which is made in the form of a level controller 19, a key 20, and a generator of sinusoidal signals 21. Input 22 is the information input of the device.

Устройство работает следующим образом .The device works as follows.

Пучок света от лазера 1 проходит через блок 2 на многоканальный моду- л тор 6, где диаметр пучка уменьшаетс  пропорционально отношению фокусных рассто ний собирающей 4 и рассеивающей 5 линз блока 2. Вышедшие из многоканального модул тора неот- клоненные и отклоненные пучки света проход т через блок 7 и отражаютс  затем качающимс  зеркалом 10, после чего проецируютс  на цилиндр 13, вращающийс  с посто нной скоростью и покрытый светочувствительным слоем.The beam of light from laser 1 passes through block 2 to multichannel modulator 6, where the beam diameter decreases in proportion to the ratio of the focal lengths of gathering 4 and scattering 5 lenses of block 2. The unbroken and deflected light beams coming out of the multichannel modulator pass through the block 7 is then reflected by the swinging mirror 10, after which it is projected onto the cylinder 13, rotating at a constant speed and covered with a photosensitive layer.

развертки заслонкой 11, поэтому он не достигает цилиндра,sweep valve 11, so it does not reach the cylinder,

Качающеесд зеркало поворачиваетс  относительно оси вращени  с а1мплиту- дой 10-30°. Отклоненный пучок перемещаетс  под действием этих колебаний по образующей цилиндра, Если модул ци  отклоненного пучка происходит синхронно с движением качающегос  зеркала 10, то образуетс  р д знаков вдоль образующей цилиндра, которые могут проецироватьс  на экран диспле .The swinging mirror is rotated about the axis of rotation with an amplitude of 10-30 °. The deflected beam moves under the action of these oscillations along the cylinder generator. If the deflected beam is modulated synchronously with the movement of the swinging mirror 10, a series of signs are formed along the cylinder generator that can be projected onto the display screen.

Смонтированный около вертикальной стороны заслонки 11 фотоприемник 12 с малой апертурой детектирует нёот- клоненный и периодически отклон емый только качаю1цимс  зеркалом лазерный луч, при этом качающеес  зеркало 10 в моменты времени, соответствую 1ще крайним угловым положени м,, выдает импульсы, которые служат дл  синхронизации модул тора 6.A small-aperture photodetector 12 mounted near the vertical side of the valve 11 detects a laser beam that is non-sloping and periodically deflected only by swinging a mirror, while the swinging mirror 10 at the time points corresponding to the extreme angular positions produces pulses that serve to synchronize the module Torah 6.

На плоскости кристалла модул тора 6 расположен ультразвуковой преобразователь (из р да дискретно расположенных сегментов 13) со сдвиговым действием. На ка одый отдельный сегмент 23 поступает сборный сигнал с усилителей 16, образуемый путем суммировани  сигналов с генераторов 21, проход щих через ключи 20 и динамические регул торы 19 на входы сумматоров 17,An ultrasonic transducer (from a series of discretely located segments 13) with a shear action is located on the plane of the modulator crystal 6. Each separate segment 23 receives a collective signal from amplifiers 16, formed by summing the signals from generators 21 passing through the keys 20 and dynamic controllers 19 to the inputs of adders 17,

Частоты генераторов распределены равномерно по всему рабочему диапа-, зону частот„The frequencies of the generators are distributed evenly throughout the working range, frequency zone “

Посредством отдельных сегментов в кристалле модул тора 6 образуютс  совмещенные фазовые решетки. Падающий под так называемым углом Брэгга пучок света отклон етс  на угол, соответствую1Щ1й отдельным частотам, и таким образом, на выходе образуютс  различные пучки света, интенсивность которых можно модулировать независимо друг от друга с помощью сиг- Нсша, подаваемого на управл ющие входы модул тора 6.By means of separate segments in the crystal of the modulator 6, the combined phase gratings are formed. A beam of light falling under the so-called Bragg angle is deflected by an angle corresponding to individual frequencies, and thus, different light beams are generated at the output, the intensity of which can be modulated independently of each other using the signal supplied to the control inputs of the modulator 6 .

В свою очередь индивидуальное управление интенсивностью каждого пучка осуществл етс  с помощью знако- генератора 14, выходные сигналы которого поступают на входы ключей 20 и динамических регул торов 19 уровн  соответствую1цих формирователей 18.In turn, the individual intensity control of each beam is carried out using the sign-generator 14, the output of which is fed to the inputs of the keys 20 and the dynamic level controllers 19 corresponding to the driver 18.

в результате этого на выходе моду л тора 6 образуютс  отклоненные пучки , формирующие колонки матрицы,as a result, at the output of the modulator 6, deflected beams are formed, forming matrix columns,

Синхронизаци  многоканальной моду л ции и качающегос  зеркала 10 может осуществл тьс  либо с помощью сигнала , с фотоприемника.12, поступающего на вход знакогенератора 14, либо с помощью сигнашов, выдаваемых знакогенератором на вход привода зеркала 10 (не показано). Вход 22 предназначен дл  организации св зи с ЭВМ.The multichannel modulation and the swinging mirror 10 can be synchronized either by a signal from a photodetector 12 inputted to the sign generator 14, or by means of signaling signals issued by the sign generator to the input of the drive mirror 10 (not shown). Input 22 is intended for the organization of communication with a computer.

Таким образом, новое конструктивное выполнение многоканального модул тора и блока управлени  позвол ет существенно упростить предлагаемое устройство и повысить надежность его работы.Thus, a new constructive implementation of a multichannel modulator and a control unit makes it possible to significantly simplify the proposed device and increase the reliability of its operation.
